Flight Path. In this problem you will use a cosine function to model the flight path of a plane that begins its descent from 20000 ft when it is 45 miles from the airport. Find the fuction p(x)= ACos(wx)+B that that gives the altitude in ft when the plane is x miles from the runway. your function must satisfy P(0)=0, P'(0)=0 P(45)=20000 P'(45)=0. if the plane is maintaining a constant horizontal velocity of 250mph, what is the maximum acceleration experienced by the passengers?
